Abstract
The utility model discloses an improved presser of a sewing machine which is provided with an end-face fixed-point rotary roller group making the pushing operation smoother. The utility model provides with a guiding device in matched way and the guiding device can guide to make the cloth go ahead along the straight line direction. The end face of the pressing board of the lower end of a presser is provided with at least a long type gutter hole according to the different requirements. The long type gutter hole is provided with at least a rotary roller group to reduce the friction force of the sewed cloth or leather so as to make the going ahead process of the sewed cloth and leather smoother. One side of the bottom part of the pressing board can be integral forming or can be provided with one guiding device in parallel way; the guiding device can also provided with the roller group to make the edge of the sewed cloth have reference for going ahead and make the sewed cloth edge or leather edge keep accordance with the sewed line not to depart from the sewed line; therefore, the utility model can reach the effect of smooth and convenient operation.
Description
The utility model relates to a kind of structure improved sewing-machine foot, be intended to improve traditional sewing-machine foot and cause the promotion that has some setbacks because of frictional force in the sewing propelling, when particularly the cloth that sewing is thicker (skin) is expected, the accurate position of any guiding of tool and not when sewing simultaneously with the visual uneven shortcoming of tape edge deflection that easily causes, be on the pressing plate of sewing-machine foot, to install at least one group wheels, slick and sly end face by wheels, when making sewing cloth through pressing plate, frictional force reduces and slides more swimmingly, then be provided with a guiding device in the bottom of this pressing plate one side or lateral margin again, make the selvedge of sewing or Pi Bianneng in a dependence,, make the thread linear state as the foundation of advancing.
During the Sewing machines sewing, the propelling of cloth or cladding relies on upper and lower pay-off to carry out fully, can be pushed into reposefully for cloth or the cladding that makes sewing therebetween, all sewing cloth is flattened in advance with a presser feet, this presser feet itself is a pressing plate and the connecting rod Joint that mat one has elasticity, is subjected to the upper and lower displacement of connecting rod to make it pressured on by sewing cloth.Yet, known presser feet is on practical operation is used, often only be even surface moulding and have an elastic acting force because of presser feet, when causing sewing cloth or cladding pushed, be subjected to the roof pressure generation frictional force of presser feet to cause having some setbacks of propelling, more obvious during especially with some thicker and coarse cloth matter of sewing, cortex.Afterwards, be that the material of people with teflon arranged, its design is placed on the presser feet, the characteristic of mat teflon smooth abrasion-proof is pushed sewing cloth or cladding swimmingly.Certainly, the people is also arranged in other lubricated modes, as: lubricating oil, be applied directly to presser feet and get off to reach smooth and easy that sewing cloth or cladding are pushed into, but, no matter with teflon or other lubricating systems, it is regular running stores, easily says it, with the lubricated increase that has on its use cost of these modes, moreover, the smooth property of teflon material is also very limited, the situation that has some setbacks so still have friction, in addition, the use of lubricating oil then easily causes the pollution to cloth (skin) material surface and thread periphery, and is dealer institute dirt disease.
Moreover, the presser feet of general Sewing machines, its effect terminates in and leans sewing cloth or cladding, there is no other effect, and it is well-known, at cloth or cladding certain sewing limit is arranged during in sewing, directly guide sewing, make its sewing limit unanimity not inclined to one side with the lines that visual cooperation hand is drawn a design along work by the genealogy of law of doing of tradition, but strictly say, the thread of so making then sees individual's proficiency entirely and decides, and in fact also can't reach consistent, and therefore the uneven situation of deflection is often arranged.
Be with, main purpose of the present utility model is to provide the sewing-machine foot of the high lubricant effect of a kind of tool, uses to make the smooth and easy of sewing cloth or cladding sewing.
Being to be to provide a kind of presser feet that guiding sewing cloth or cladding sewing advance that has with, another purpose of the present utility model, is to make the sewing limit can have foundation of a spacing to advance, when making sewing with accurately, make things convenient for.
According to sewing-machine foot of the present utility model, owing to have guiding, accurate and convenient when making sewing.
Now with regard to structure of the present utility model and principle of work and power conjunction with figs., enumerate preferable embodiment and be described in detail as follows, make the utility model more clear:
